Preston resident troopers on Thursday arrested a Voluntown man on multiple drug charges after stopping him for allegedly driving an unregistered vehicle.

Troopers were conducting a driving under the influence patrol in the area of routes 164 and 165 when they stopped Michael Falade, 28, of 39 Valley Drive in Voluntown, about 5:30 p.m.

During the stop, troopers smelled a "strong odor of marijuana," state police Troop E said in a press release, and performed a narcotics search, which turned up "a substanstial amount" of marijuana in two bags, drug paraphernalia and drug manufacturing equipment.

Falade was charged with possession of narcotics, possession of drug paraphernalia in a drug factory, sale of a controlled substance and possession of drug paraphernalia. He was held on a $5,000 non-surety bond and is due in Norwich Superior Court on Aug. 1.
